Eaton 3400X12 90 Degree Street Elbow 3/4 in Brass

Product Description

The EATON 3400X12 is a 90-degree street elbow fitting designed for industrial pipe systems requiring a compact directional change in a single connection. It features a 3/4 inch male NPT thread (MNPTF) on one end and a 3/4 inch female NPT thread (FNPTF) on the other, allowing it to thread directly into a fitting or valve without a separate nipple. Constructed from brass, this elbow is rated for a maximum working pressure of 1,200 psi and handles temperatures from -65 degrees F to 250 degrees F. It is sold individually and is suitable for use in pressurized fluid and gas piping assemblies.

This street elbow is used in residential and commercial plumbing, HVAC, and industrial piping applications where a 90-degree turn is required in tight spaces. The street configuration eliminates the need for an additional close nipple, making it a practical choice when routing pipe through confined areas. Licensed plumbers and pipefitters install this type of fitting in water, air, oil, and compatible fluid service lines where brass construction and NPT threading are specified.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing codes. Depressurize and isolate the affected line before removing any existing fittings. Apply appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten brass fittings, as brass threads can be damaged by excessive torque.
